Abstrakt: One of the new trends of computer process control is the distributed control using microcomputers. There are two alternatives of the distributed organization: the coordinated and the hierarchical one. Our object was to develop a multiprocessor microcomputer which can be configured and programmed as an intelligent control station or dispatcher center in a distributed hierarchical process control system. The nucleus of the system is a universal real-time multitask monitor. One CPU provides the monitor functions to simplify the organization. Each CPU has its own RAM and ROM memory. The multiprocessor system has a common memory to provide the communication of programs. The micromonitor can solve synchronization and timing problems by handling events, resources and a HT clock with a resolving power of 10 ms. The microcomputer was constructed from Intel 8080 CPU-s and LSI chips of the with 2 to 4 CPU-s; the minimum-size micromonitor occupies 2 Kbytes ROM.
